It all depends on the weather as too how quickly the motor cools down. Normally though if it's been standing for more than 1 hour I always let it tick-over for about 30 seconds before I give it some welly. This gives time for the oil to reach the rockers.

The "warm up" generally applies to a cold engine that has been stood for a few hours or more. 10-15 minutes shouldn't make much difference at all. The oil won't be completely evacuated in that time, probably not for a few hours? Use the temp gauge as a guide. Don't pull away until the gauge is registering.

S4R's...............still bust rockers unfortunately, especially if you rev it from cold

In summary - they built a motor with a special cam in it and it happened that the oilway plug was not fitted to that particular cam and they didn;t realise it. 90 seconds after starting the engine the oil started coming out of the end of the cam. Hence the estimate of 90 seconds from cold to get the oil up to the rear cylinder.

At this time of year i generally give it about 6 months to warm up, SAD Innit waiting for next spring

Nelly at Cornerspeed can supply you with a side stand over ride so the engine runs with the stand down (only in neutral of course to prevent trying to ride away) so bike can warm up for 90 seconds while getting gloves and helmet on.

They reckon you shouldn't over do the warm up period. I used to let it get too hot I think when I first got the ST2, but I've seen it said enough times to let the temp guage get a reading (as Nelly said) but dont let it get really hot on idle. Even when it's warm I start it and then put my helmet and gloves on. Gives you something to do while the oils circulating.
